Removable Display Docking for Construction Machine Operator Console
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional operating devices for construction machines, such as road finishing machines, are limited by their fixed display units that can only be viewed by operators in proximity and are restricted to displaying operating parameters only, lacking multifunctionality and portability.
Innovation Solution
An operating device with a docking station that allows a portable display unit, such as a tablet computer or smartphone, to be securely attached and detached without tools, enabling wireless operation and providing additional features like camera functionality, remote control capabilities, and data exchange, while preventing theft and protecting the display from environmental damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display unit is integrated into the operating device, then the operator can view operating parameters during operation, but the display unit cannot be removed and is limited to displaying only operating parameters
Solution Approach 1:
The display unit is separated from the operating device into an independent removable component. This segmentation allows the display unit to be detached and used independently as a portable device, enabling it to perform multiple functions beyond just displaying operating parameters, while the operating device retains its core functionality without the added complexity of an integrated display system.
Solution Approach 2:
The display unit is designed to function both as an integrated display when connected to the operating device and as a standalone portable device with additional functionalities such as camera, GPS, and media player. This multi-functionality increases adaptability without requiring permanent integration into the operating device structure.
2Adaptability or versatility
If the display unit is permanently mounted in the operating device, then it is securely positioned, but it cannot be taken away for portable use or protection from environmental damage
Solution Approach 1:
The connection between the display unit and operating device is made dynamic rather than fixed. The display unit can be connected when needed for operation and disconnected when portable use or protection from environmental damage is required. This dynamic connection allows the system to adapt between secured stationary use and mobile protected use.
3Ease of operation
If the display unit is integrated into the operating device, then it provides real-time operating information, but it limits the operator to being in direct proximity of the operating device
Solution Approach 1:
The display unit is extracted from the fixed position in the operating device, allowing it to be removed and carried by the operator. This extraction enables the operator to access operating information and control functions from various locations, not just when standing directly at the operating device, thereby improving ease of operation and usage flexibility.

AI summary
An operating device for a construction machine includes a plurality of operating elements for adjusting operating parameters of the construction machine, and a display unit which is configured to display technical data. The operating device further comprises a docking station at which the display unit is attached so as to be removed without tools and which is provided for connecting the display unit with at least one data line and/or power supply of the construction machine.
